A reactor or mixing tank is often at the heart of the process where chemicals are made, requiring reliable and accurate level measurement to ensure high quality, control and consistency of product. In reactor vessels, conditions can be harsh with quickly changing levels, turbulence, changing temperatures and viscous or corrosive media. With the reactor often fitted with agitators, non-contacting radar combined with point level detection technology is ideal for minimal intrusion into the vessel, avoiding obstructions.
Radar level transmitters using different frequencies are needed to solve different process challenges within reactors and mixing tanks. Higher frequency level transmitters such as the 80GHz Rosemount 3408 are suitable for small process fittings and short measuring ranges, while the mid frequency of 26 GHz Rosemount 5408 better suits the more challenging process conditions including presence of vapor and foam.
